add lazy_load_hooks.rb, which allows us to declare code that should be run at some later time. For instance, this allows us to defer requiring ActiveRecord::Base at boot time purely to apply configuration. Instead, we register a hook that should apply configuration once ActiveRecord::Base is loaded. With these changes, brings down total boot time of a new app to 300ms in production and 400ms in dev.
